[0002] The eccentric connecting rod vibrating conveyor is a key auxiliary equipment in the tobacco industry's tobacco production line. Its main function is to use the eccentric connecting rod mechanism to vibrate the trough to complete the tasks of conveying and screening tobacco leaves or tobacco shreds.

[0003] Because the eccentric assembly of the eccentric connecting rod vibrating conveyor needs to be replaced regularly, the eccentric angle refers to the angle between the line connecting the maximum eccentric point and the axis and the center line of the trough. Because these two straight lines are not in the same plane, the eccentric angle of existing measuring tools cannot be directly measured. When measuring the eccentric angle, maintenance personnel rely on experience and eyes to observe the angle between the maximum eccentric point and the axis. Due to the large diameter of the eccentric connecting rod, large pitch and low adjustment accuracy, this method requires repeated operations, is very troublesome, takes a long time to repair and maintain, and has low maintenance efficiency. In addition, improper adjustment will cause eccentric overheating and abnormal noise, causing certain damage to the equipment. Utility Model Content
